theshadowx/qt5.4-nacl repository overview
DockerFile Qt5.4 NaCl
DockerFile to generate a base image for ubuntu 14.04 with Qt5.4 and NaCl
Building dockerfile
In a termial go to the folder where have put Dockerfile.
Execute this command :
$ sudo docker build -t qtnacl5.4.2 .
It will take a lot of time !!! Then execute this command to run a container :
$ sudo docker run -it qtnacl5.4.2 bash
Using image from Docker Hub
Pull the image
$ docker pull theshadowx/qt5.4-nacl
Run a container
$ sudo docker run -it theshadowx/qt5.4-nacl bash
How to build and deploy your application
So you have made your application and you want to build and deploy it using "QtNaCl", I think the best way is to mount the folder containing the project as a Data Volume so that you could read/write data directly to the project folder.
N.B. : you have to use the full path to "qmake and nacldeployqt" in order that some QML/Qt files would be generated, otherwise you will have a blank window in the browser when you deploy the application.
Generating Makefile
$ docker run --rm -it -v /path/to/ProjectFolder:/data/example theshadowx/qt5.4-nacl bash -c "mkdir /data/example/build/ && /opt/QtNaCl_5.4/qtbase/bin/qmake /data/example -o /data/example/build/"
Building
$ docker run --rm -it -v /path/to/ProjectFolder:/data/example theshadowx/qt5.4-nacl bash -c "cd /data/example/build && make"
Deploying
$ docker run --rm -it -P -v /path/to/ProjectFolder:/data/example theshadowx/qt5.4-nacl:OoS_Qt5.4.2_NaCl42 bash -c "cd /data/example/build && /opt/QtNaCl_5.4/qtbase/bin/nacldeployqt ProjectName.bc --run"
Now the app is listening to port 8000
Deploying "nacl.bc"

In another terminal :
$ docker ps
| CONTAINER ID | IMAGE | COMMAND | CREATED | STATUS | PORTS |
|---|---|---|---|---|---|
| 834315034c8c | theshadowx/qt5.4-nacl | "bash -c 'cd /data/ex" | 24 seconds ago | Up 23 seconds | 0.0.0.0:32772->8000/tcp |
Here the port is 32772
Chrome Browser
Open the chrome browser and put the following address (depending on the IP and the port you got from precedent steps)
http://172.17.42.1:32772
When you launch the app for the first time, you'll have to wait some seconds; But after that, it will be instantaneous.
